The main objective of this work is to assess the environmental impact and
investment feasibility analysis of rainwater harvesting systems for a low-cost
house located in Florianópolis, southern Brazil, by using the concepts of Life
Cycle Analysis (LCA).
The environmental and investment feasibility analysis
was performed for two scenarios, i.e., a scenario in which there is only a potable
water system supplied by the water utility, and another scenario in which the
potable water system is complemented by rainwater.
Three types of rainwater
storage tanks were analysed: plastic reinforced with glass fibre, high density
polyethylene and reinforced concrete.
Results indicate that plastic tanks
reinforced with glass fibre are environmentally more feasible, while concrete
tanks are economically more feasible.
This study showed the importance of
analysing environmental and economic aspects before implementing a system
with rainwater utilization; thus better choices regarding the materials used in the
systems, aiming at sustainability in buildings, can be made.
